Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed March 12, 1904. Serial No 197,875.

ough of Manhattan, city and State of New bon copies has been to take as many carbonsheets and plain sheets as the number of copies desired and to arrange them into a collection of loose leaves wherein the carbon-sheets and plain sheets alternate. Such an arrangement, however, is objectionable in that considerable work is involved in placing the leaves together accurately, and the handling of the carbon-sheets is disagreeable, as it soils the fingers. According to our invention each plain sheet, except the original, is joined to another sheet, the surface of which is thinly carbonized upon its inner surface, the carbon surface being suflicient to produce one good copy, When the duplex sheet thus formed has been used, the carbon-sheet is detached and discarded- For the purpose of enabling our arrangement to be employed for producing a greater number of carbon copies of successive operations we employ a number of loose plain sheets between the duplex sheet.

Reference is hereby made to the accompanying drawings, in which Figurel is an edge view of one form of our invention. Fig. 2is a plan View of the duplex sheet of Fig. 1, the plain leaf being partly broken away to show the carbon-leaf which ordinarily lies above it. Fig. 3 is a broken view of the central portion of the duplex sheet, showing the plain and carbon leaves opened out. Fig. 4 is an edge view of a slight modification of the duplex sheet of Fig. 1. Fig. 5 is a plan view similar to Fig. 2 of the duplex sheet shown in Fig. 4. Fig. 6 is an edge view of a further modification of our invention, and Fig. 7 is a perspective view of the arrangement of Fig. 6 with a letter-head superimposed thereon to receive the original impression.

The manifolding-sheet shown in Figs. 1, 2,

and 3'consists of a single sheet of paper folded at or near a central transverse line, forming two leaves 1 and 2. The leaf 1 is carbonized upon its inner surface, as shown, and leaf 2 is left plain to receive a carbon impression from the leaf 1. We also preferably, although not necessarily, provide a line of perforations 3 at or near the line of fold. The carbonized surface of leaf 1 is designed to make butasingle copy-namely, that upon the leaf 2-and for this reason may be very cheaply made.

leaves 1 and 2 are made of separate sheets cementing material, and a line of perforations 3 may also be provided.

In using either of the forms of manifoldingsheets just described the user selects a plain sheet or letter-head to receive the original .impression and as many of the duplex sheets as he desires carbon copies. These sheets may be very easily assembled and placed in the machine. Thus if an operator desires to make one, two, three, or four carbon copies only two to five loose sheets would be handled that'is, the single sheet for the original copy and one or more duplex sheetswhile as heretofore practiced the operator would handle one sheet for the original copy plus one carbon-sheet and one plain sheet for every carbon copy desired, or, in other words, three to nine loose sheets. Considerable care is required to insert these sheets evenly in the type-writer carriage and much time is lost. Upon removal from the type-writer the leaves 1 and 2 or 1 and 2 are torn apart along the weakened line, which may be either the perforations or the line of fold, and the carbon- 'leaves 1 and 1. may then be discarded.

In the form shown in Figs. 6 and 7 a duplex sheet similar to those of Figs. 1 and 4 is used. Between the leaves 1 and 2 a number of plain loose sheets or leaves 5 are inserted of any convenient number, as ten, for instance. The carbon-surface of the leaf 1 should be capable of making ten separate impressions or as many impressions as there are loose sheets 5. When using the manifolding-sheets in that way, a loose sheet or letter-head 6 is placed above leaf 1, as shown in Fig. 7, and the device is then inserted in the type-writing machine. A carbon copy of the matter written on the original sheet 6 will be made on the first loose sheet 5 that is, the one next to the carbon-face 1. Upon removing the sheets In the form shown in Figs. 4 and 5 the of paper secured together at 4 by a suitable from the machine the original and the carbon copy are removed, and the manifolding-sheets are then ready for further use with another loose sheet or letter-headupon which to write the original and may be used until all the leaves 5 have been exhausted.

' What we claim is As a new article of manufacture, a manifoldsheet for type-Writing comprising a long sheet of paper having a coating of carbon on one side covering the entire width and one-half the length of the sheet and folded Where the carbon-surface ends so as to form a duplex sheet with the carbon-surface on the inner side. and a number of plain sheets placed between the parts of said duplex sheet and the whole designed to be inserted in a type-writanother letter-head or the like after removing the carbon copy previously made.
